This is the start of my second S550 V6 project. For some that do not know, I went from a 2015 V6 with 110k miles up to a new 18 GT in May 2018. Unfortunately, in December, my 18 was totaled... My replacement is what you see below, a 2016 051A V6 Deep Impact Blue with 29k miles. Got the car for less than 17k in perfect condition which effectively halves the cost of the car comparted to the GT. My ambitious plan for this car is to make the Mustang Ford would not, a Premium Ecoboost V6. I also plan on some body mods like an 2018 rear bumper and possibly 2018 style front clip (with non-stock bumper) since I already have a few 18 parts. The project is just starting so the mod list is not fully together but will be coming soon!

Went ahead and ordered the pypes H-bomb catback to replace the terrible stock exhaust! 3" OD piping is overkill for an NA 6 but should work quite well with the turbo setup. Immediate plan is to work on acquiring supporting mods for the turbo setup like GT TB, 350 Intake box, High Flow catted down pipes, etc...

Also coming soon is the LCD Cluster! Got this cluster off of ebay for an excellent price and am currently working on acquiring the rest of the parts to complete the swap. Here is a teaser of the cluster in action in the V6! (the RPM gauge was not working but will work after programming)

Well guys bad news.... The pypes H-bomb sounds terrible.... It's way to loud in all the wrong areas. It basically sounds like a straight pipe from the headers. Going to swap in some magnaflow mufflers tomorrow or Sunday in place of the resonators of the kit. Hopefully that will fix it. The benefit is I still get 3" piping.

Current exhaust revision. This setup consists of the Pypes GT H-Bomb Catback modified with Magnaflow 4" round mufflers. I will be adding shorty headers and high flow catted mids soon. After these are added I will decide if I stick with an H or go with an X instead.

Shorty Headers ordered! Went with the "eBay" specials since people seem to have had decent luck with them and $100 is alot nicer then $350 for BBK.

It is looking like I will be going the route of Eaton M90 for boost as I think it has the potential to be a very easy and low impact (not very intrusive and not requiring alot of mods to the vehicle itself) way to add boost. Plus the benefits that come from a roots style blower such as near instant torque and better power curve. The M90 should not fall off at the top like the 3.5 EB turbos would. Upgrades to the 3.5 turbos were proving to be a very expensive path.

Hope you can get it to work without much trouble or a big cowl hood! With your background/job, might be easier for you to troubleshoot during development and I'm sure if the price is right afterwards, you might get a few people interested in buying as well.

For the dash, what search terms were you using on ebay to find it? If I can get that kind of deal, I'll jump on it too, just looks awesome in there.

Just ordered about everything needed for an 80mm TB conversion. I think I am going to hold off on an actual tune right now until I get the FI build going. Does not make much sense to spend $100 for an NA tune and then another $600 for an FI tune. I will just skip straight to the FI tune.

Depends on who you go with, I don't know how good his tunes are, but Auto Mafia has a $600 tunes for life program now...includes FI but no experience with a roots SC on our cars obviously! The trans tuning from MPT really wakes the car up though so I think it's a worthwhile $100.

Yea that is the thing I am trying to decide on.... I am thinking about sticking with MPT since I was pretty pleased with their tunes before and they have the most experience I think with FI 3.7s. The final decision will come down to if the FI build is happening soon or if it will be awhile.
